Liquid chalk is used to improve grip during exercises such as weightlifting, gymnastics, climbing or strength training.
It is applied directly to the hands, where it dries quickly to form a layer that reduces palm sweating and increases friction. This provides a firm and stable grip, which helps when lifting heavy weights or gripping the bar.

Liquid chalk is also advantageous because it doesn’t leave a mess like traditional powdered chalk, and is often allowed in gyms where regular chalk isn’t used.
